Figure 2
Experimental EXAFS and DiffEXAFS for the Fe and Sr K-edges of α-Fe (top graph) and SrF2 (bottom graph) at room temperature. ΔT for each difference spectrum is shown on the right, and is set to an accuracy of ±0.2 K. The grey plots are the inverted gas jet phase-reversed signals, which are essentially identical to the black plots, proving the thermal origin of the signal. The dashed vertical lines, which are centred on peaks in the EXAFS plots, highlight the phase shift of the difference signals with respect to the EXAFS.
